But, your DON'T is _not_ related in any way to Forth's DO ...

Or, what's wrong with a DON'T ... LOOP ?

I think hear some laughter, but I'm not joking ...

Perhaps, DON'T could define a range to skip in a LOOP.
E.g., modified "Starting Forth" example for DO ... LOOP:

10 0 3 7 DON'T  I .  LOOP

0 1 2 7 8 9

It might be implementable with a conditional +LOOP when I is 3 ... ?

I have no serious thoughts on the order of 3 7 is 3 7 or 7 3 or
whether 3 or 7 are inclusive or exclusive.  Your choice.

Also, not to be finicky, but would you really put an apostrophe
in the name of a FORTH word?  Yes, we have ' (tick) ['] but otherwise ...
